      Lesson 6: Reliability Analysis. Reliability means consistency. It is the degree to which an instrument will give similar results for the same individuals at different times. Reliability can take on values of 0 to 1.0, inclusive. Methods for checking Reliability: Test-retest reliability. The calculation of test-retest reliability is straightforward.

      (Gay) Reliability is the degree to which a test consistently measures whatever it measures. Errors of measurement that affect reliability are random errors and errors of measurement that affect validity are systematic or constant errors. Test-retest, equivalent forms and split-half reliability are all determined through correlation.
